House of the dead Overkill Not supported?

[ReaverXIII]

I spent the last few hours to try differents iso / rvz even few i've done myself by dumping my own physical game, but everytime, even after forcing uknown files format, i got this error:

The House of the Dead Overkill USA .rvz (or .iso) None compression is currently not supported

Any idea on how to fix this?

rvz are only supported with Zstandart. None compression is not implemented yet. Either you convert it as an iso or you unpack the game as a folder.
